Imagine checking your health status from blood, sweat, or even tears—without ever stepping into a clinic. Advances in digital diagnostics are making at-home testing a reality, allowing patients to analyze their bodily fluids with smart devices and wearables.
From blood tests on menstrual pads (Qvin’s Q-Pad) to real-time hydration tracking via sweat (Epicore Biosystems’ Gx Sweat Patch), cutting-edge innovations are revolutionizing early disease detection, fertility tracking, and chronic disease management. Even at-home urine tests can now screen for kidney disease and UTIs with FDA-cleared kits like Healthy.io and Withings’ U-Scan.
While some efforts—like Verily’s smart contact lenses for glucose monitoring—have stalled, the bodily fluid revolution is far from over. With AI-powered diagnostics on the horizon, could a single drop of sweat or saliva soon predict disease before symptoms even appear?
